What I do

The work that makes
AI systems trustworthy

Schema & Ontology

Ontology &
Schema Design

Designing the conceptual frameworks that give your data meaning. Entity models, relationship structures, taxonomies, and metadata frameworks built for graph-based reasoning and machine discovery — the foundation on which everything else rests.

Quality & Governance

Data Quality
& Governance

Establishing the standards that make your data trustworthy. Validation processes, provenance tracking, auditability frameworks, and compliance reviews that satisfy regulators and underpin reliable, explainable AI systems.

Classification & Enrichment

Entity Resolution
& Enrichment

Transforming raw data into structured knowledge. Entity resolution, normalization, controlled vocabularies, and metadata strategies that support both human understanding and machine reasoning — turning noise into signal.

AI & RAG

AI & RAG
Data Architecture

Preparing data for the systems that depend on it. Structuring knowledge bases, graphs, and retrieval layers so your AI agents, RAG pipelines, and LLMs perform with precision — and can explain what they know and why.

About

Where precision
meets intelligence

Datenvalue is an independent data architecture practice working at the intersection of ontology engineering, semantic data design, and AI data governance.

With over 20 years of experience structuring information for the systems that depend on it, I work with organisations building AI systems, knowledge graphs, and intelligent pipelines where data quality, verifiability, and governance are not optional.

Current engagements include government-funded AI and space intelligence programs requiring robust, auditable, and machine-ready data infrastructure.
